Managing Veeam backups in the EU brings challenges of cost unpredictability and complex data laws. A sovereign, S3-compatible storage target offers a clear path forward, ensuring compliance and control.

Key Takeawys

Using a European provider for Veeam backups eliminates US CLOUD Act exposure and ensures full GDPR compliance by design.

A storage model without egress or API fees provides cost predictability and stable margins, removing billing surprises during data restores.

Full S3 Object Lock compatibility allows Veeam to create immutable backups, securing data from ransomware modification or deletion.

For IT leaders and MSPs using Veeam, selecting the right backup target is a critical decision with long-term consequences. Storing data with non-EU providers creates exposure to foreign laws like the US CLOUD Act, even when using European data centers. This guide details the advantages of choosing European Veeam S3 compatible target storage solutions. It focuses on achieving digital sovereignty, cost predictability, and robust ransomware defense. We explore how a modern architecture simplifies compliance with GDPR and prepares you for the EU Data Act of 2025.

Secure Veeam Data Within an EU-Sovereign Storage Framework

Storing backup data within the EU is a primary requirement for GDPR compliance. This ensures data processing aligns with strict European privacy laws from day one. Many organizations find that using a US-based provider, even with EU data centers, creates a direct conflict with the US CLOUD Act. This 2018 law permits US authorities to demand data regardless of its physical storage location.

A truly European provider eliminates this legal ambiguity entirely. By design, data remains under EU jurisdiction, offering legal certainty that a significant majority of EU decision-makers now demand. Choosing a sovereign S3-compatible object storage provider is the first step toward building a resilient and compliant backup strategy. This approach ensures your most critical data assets are protected by EU law.

This foundation of sovereignty directly impacts your ability to manage risk and meet regulatory demands.

Eliminate Unpredictable Costs in Your Veeam Backup Strategy

The total cost of ownership for backup storage often includes surprising expenses. Many cloud providers charge significant egress fees for data retrieval, turning a routine restore operation into a major cost event. Recovering just 10TB of data can generate hundreds of dollars in unexpected fees alone.

A predictable pricing model transforms budget management for the better. Leading predictable MSP margins are built on storage with no egress fees, no API call charges, and no minimum storage durations. This transparency allows for accurate financial planning and removes the fear of initiating large-scale recoveries. A zero-egress model means you only pay for the storage you use.

Here are four hidden costs that a transparent model helps you avoid:

  • Fees for retrieving your own data during a recovery.

  • Charges for API calls made by Veeam for routine backup tasks.

  • Penalties for deleting data before a minimum duration has passed.

  • Complex tiering costs that appear during urgent restore requests.

This economic clarity is essential for building a scalable and sustainable backup infrastructure.

Leverage Advanced S3 Compatibility for Seamless Veeam Integration

True enterprise-readiness requires more than basic S3 API support. A fully compatible solution ensures all of Veeam’s advanced features work flawlessly without code rewrites or complex workarounds. This includes support for versioning, lifecycle management, and S3 Object Lock for immutability. These out-of-the-box integrations protect your past investments in scripts and workflows.

An “Always-Hot” storage architecture further simplifies operations. This model ensures 100% of your data is immediately accessible without delays in restoring data from colder, slower tiers. This eliminates the operational complexity and hidden restore fees associated with fragile tiering policies. It guarantees consistent, predictable performance whether you are accessing millions of small files or large backup chains. This architectural choice is key to maintaining stable third-party tool performance.

With a reliable and consistent architecture, you can focus on strengthening your data protection policies.

Implement Immutable Veeam Backups for Ransomware Defense

Ransomware attacks increasingly target backup files to prevent recovery. Veeam leverages S3 Object Lock to make backups immutable, meaning they cannot be altered or deleted for a predefined period. This feature is a cornerstone of modern data defense, creating a secure copy of your data that is impervious to malicious encryption. It provides a guaranteed clean recovery point after an incident.

This capability enhances traditional backup strategies like the 3-2-1 rule. By making one copy of your data immutable, you add a powerful layer of resilience. A 30-day immutability period ensures your recent backups are always safe. Using Immutable backups with Object Lock is a non-negotiable part of any serious security posture.

Follow these four steps to enable immutability in your Veeam environment:

  1. Create a new S3 bucket with Object Lock enabled in your provider's console.

  2. Add the bucket as a new object storage repository within the Veeam Backup & Replication console.

  3. During setup, select the checkbox to make backups immutable for a specific number of days.

  4. Configure your backup or backup copy jobs to target this new immutable repository.

This proactive security measure prepares you for emerging regulatory requirements.

Future-Proof Storage for the EU Data Act and NIS-2

New EU regulations taking effect from September 2025 will reshape data governance. The EU Data Act requires cloud providers to remove switching barriers, making data portability a legal right to combat vendor lock-in. A provider built on open standards and exportable formats aligns perfectly with this mandate. It ensures you maintain negotiation power and long-term freedom.

Simultaneously, the NIS-2 directive expands cybersecurity obligations for many businesses. It mandates continuous security processes, supply-chain assurance, and strict incident reporting timelines. Using compliant Veeam storage solutions from a European provider helps fulfill these supply-chain security duties. This turns regulatory readiness into a competitive advantage. You can demonstrate a secure and documented data management process to auditors and customers.

These compliance benefits extend directly to the partner ecosystem.

Empower MSPs with a Partner-Ready Veeam Storage Target

For MSPs and resellers, predictable margins are essential for profitability. A storage model with zero egress or API fees provides a stable cost base for building Backup-as-a-Service offerings. This design allows partners to offer competitive pricing without risking surprise charges during client restores. The platform is built to support a growing channel with a multi-tenant console and robust automation via API/CLI.

Onboarding is designed to be fast, enabling partners to deploy solutions in minutes. The partner console offers full RBAC and MFA for secure multi-tenant management. Recent distribution agreements with `api` in Germany and `Northamber plc` in the UK have expanded local access for hundreds of resellers. This momentum provides partners with the resources and cloud storage for MSPs needed to scale their Veeam services effectively.

Now is the time to evaluate your storage strategy and take practical steps toward a more sovereign and predictable future.

FAQ

What makes a storage solution 'Sovereign by Design'?

A 'Sovereign by Design' storage solution is one that is owned, operated, and located exclusively within a specific legal jurisdiction, like the EU. This ensures that your data is governed only by local laws, such as GDPR, and is not subject to foreign legislation like the US CLOUD Act.



Is S3 Object Lock essential for ransomware protection?

Yes, S3 Object Lock is a critical feature for modern ransomware protection. It allows Veeam to create immutable backups that cannot be encrypted, modified, or deleted by attackers, ensuring you always have a clean copy of your data for recovery.



How does the EU Data Act affect my choice of a Veeam backup target?

The EU Data Act, effective from September 2025, mandates that cloud service providers must make it easy for customers to switch to another provider without technical or financial penalties. Choosing a provider that already uses open standards and has no lock-in mechanisms ensures you are compliant and retain control over your data.



Can I use this storage for more than just Veeam backups?

Absolutely. A fully S3-compatible object storage solution can be used for a wide range of use cases beyond backups, including archiving, tape-to-cloud initiatives, and as a storage backend for any application that uses the S3 API.



What is an 'Always-Hot' storage model?

An 'Always-Hot' storage model means all data is stored on a single, high-performance tier and is immediately accessible. This eliminates the delays and complexities of tiered storage, where data must be moved from 'cold' or 'archive' tiers before it can be accessed, which often incurs extra fees and slows down restores.



How does a zero-egress-fee model benefit MSPs?

For MSPs, a zero-egress-fee model provides complete cost predictability. It allows them to build and price Backup-as-a-Service (BaaS) offerings with stable, defensible margins, without the risk of unexpected data retrieval costs eroding their profits during a client recovery.
